Question

How do you factor `3s^3+6s^2+5s+10`?

Answer 1

`(s+2)(3s^2+5)`

Explanation:

There are 4 terms but there is no common factor in all the terms, Group them in pairs to create common factors.
Make sure there is a + sign between the pairs.

`(3s^3+6s^2)+(5s+10)`

=`3s^2(s + 2)+ 5(s +2)" common bracket"`

=`(s+2)(3s^2+5)`
